Figure 4From: Stage-specific fluorescence intensity of GFP and mCherry during sporulation In Bacillus SubtilisThe pH-dependent emission profile of GFP and mCherry. GFP is more sensitive to pH change than mCherry. The pH-dependent emission profile of GFP and mCherry was investigated by resuspending GFP and mCherry in phosphate buffers with a pH ranging from 4.4 to 9.1. The emission was then plotted against the pH value to obtain the profile.Back to article page
